### e_dbus_source_writable_call_write_sync ()

    gboolean
    e_dbus_source_writable_call_write_sync
                                   (EDBusSourceWritable *proxy,
                                    const gchar *arg_data,
                                    GCancellable *cancellable,
                                    GError **error);

Synchronously invokes the `Write()` D-Bus method on `proxy` . The calling thread is blocked until a reply is received.

See `e_dbus_source_writable_call_write()` for the asynchronous version of this method.

#### Parameters

proxy | A EDBusSourceWritableProxy. |
arg_data | Argument to pass with the method invocation. |
cancellable | A GCancellable or `NULL`. | [allow-none]
error | Return location for error or `NULL`. |

#### Returns

`TRUE` if the call succeded, `FALSE` if `error` is set.

### e_dbus_source_writable_call_write ()

    void
    e_dbus_source_writable_call_write (EDBusSourceWritable *proxy,
                                       const gchar *arg_data,
                                       GCancellable *cancellable,
                                       GAsyncReadyCallback callback,
                                       gpointer user_data);

Asynchronously invokes the `Write()` D-Bus method on `proxy` . When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call `e_dbus_source_writable_call_write_finish()` to get the result of the operation.

See `e_dbus_source_writable_call_write_sync()` for the synchronous, blocking version of this method.

#### Parameters

proxy | A EDBusSourceWritableProxy. |
arg_data | Argument to pass with the method invocation. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |
user_data | User data to pass to `callback` . |

### e_dbus_source_writable_call_write_finish ()

    gboolean
    e_dbus_source_writable_call_write_finish
                                   (EDBusSourceWritable *proxy,
                                    GAsyncResult *res,
                                    GError **error);

Finishes an operation started with `e_dbus_source_writable_call_write()`.

#### Parameters

proxy | A EDBusSourceWritableProxy. |
res | The GAsyncResult obtained from the GAsyncReadyCallback passed to `e_dbus_source_writable_call_write()`. |
error | Return location for error or `NULL`. |

#### Returns

`TRUE` if the call succeded, `FALSE` if `error` is set.

                                           GDBusMethodInvocation *invocation);

Helper function used in service implementations to finish handling invocations of the `Write()` D-Bus method. If you instead want to finish handling an invocation by returning an error, use `g_dbus_method_invocation_return_error()` or similar.

This method will free `invocation` , you cannot use it afterwards.

#### Parameters

object | A EDBusSourceWritable. |
invocation | A GDBusMethodInvocation. | [transfer full]

## Types and Values

### EDBusSourceWritable

    typedef struct _EDBusSourceWritable EDBusSourceWritable;

Abstract interface type for the D-Bus interface org.gnome.evolution.dataserver.Source.Writable.

### struct EDBusSourceWritableProxy

    struct EDBusSourceWritableProxy;

The EDBusSourceWritableProxy structure contains only private data and should only be accessed using the provided API.

### struct EDBusSourceWritableSkeleton

    struct EDBusSourceWritableSkeleton;

The EDBusSourceWritableSkeleton structure contains only private data and should only be accessed using the provided API.

## Signal Details

### The `“handle-write”` signal

    gboolean
    user_function (EDBusSourceWritable   *object,
                   GDBusMethodInvocation *invocation,
                   gchar                 *arg_data,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Write()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_source_writable_complete_write()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusSourceWritable. |
invocation | A GDBusMethodInvocation. |
arg_data | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last
